|Other Names||[Pyruvate dehydrogenase (acetyl-transferring)] kinase isozyme 2, mitochondrial, Pyruvate dehydrogenase kinase isoform 2, PDH kinase 2, PDKII, PDK2, PDHK2|
|Target/Specificity||A synthetic peptide corresponding to residues near the N-terminus of human PDK2 was used as an immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||PDK2 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Kinase that plays a key role in the regulation of glucose and fatty acid metabolism and homeostasis via phosphorylation of the pyruvate dehydrogenase subunits PDHA1 and PDHA2. This inhibits pyruvate dehydrogenase activity, and thereby regulates metabolite flux through the tricarboxylic acid cycle, down-regulates aerobic respiration and inhibits the formation of acetyl-coenzyme A from pyruvate. Inhibition of pyruvate dehydrogenase decreases glucose utilization and increases fat metabolism. Mediates cellular responses to insulin. Plays an important role in maintaining normal blood glucose levels and in metabolic adaptation to nutrient availability. Via its regulation of pyruvate dehydrogenase activity, plays an important role in maintaining normal blood pH and in preventing the accumulation of ketone bodies under starvation. Plays a role in the regulation of cell proliferation and in resistance to apoptosis under oxidative stress. Plays a role in p53/TP53-mediated apoptosis.|
|Cellular Location||Mitochondrion matrix.|
|Tissue Location||Expressed in many tissues, with the highest level in heart and skeletal muscle, intermediate levels in brain, kidney, pancreas and liver, and low levels in placenta and lung|

A member of Pyruvate dehydrogenase kinase (PDK1, 2, 3, and 4), PDK2 is a serine kinase which is involved in the regulation of mammalian glucose metabolism. During aerobic energy metabolism, mitochondrial pyruvate dehydrogeanse complex (PDC) catalyzes decarboxylation of pyruvate to form acetyl-CoA (1). PDK2 inhibits PDC thru phosphorylation of the E1 alpha subunit of PDC and inactivates the complex (2). Highly expressed in heart and skeletal muscles, PDK2 is also responsible for the phosphorylation of Akt at Ser473, which leads to phosphorylation by PDK1 on Thr308 on Akt and full Akt activation (3).
